Roger,

Try changing the O2 sensor first, while not cheap, they are cheaper
than an ECU!  You can get a universal 3-wire O2 sensor at a FLAPS and
wire it in yourself, or any of the list vendors can help you with an
original or "splice it yourself" model.

If the O2 sensor doesn't help, let me know and I can loan you my spare
ECU to make sure that corrects the problem (before you spend $$$$)!
